How do know that a boy is crushing on you?

Well , if he is looking at you and laughing at your jokes, then he must have a crush on you, if you also have a crush on him, just go and talk to him.

he will know you have a crush on him. I'm eleven years old and that is how i got my BF Ryder when i had a crush on five boys and did not know who to go with.We've been dating for seven months.(remember to give your BF a present or kiss him.) I've kissed Ryder like 17 times.or more.
